ERMAHGERD NEW DRAFT. Yes, since the horrible ████ of ███ and █████ with a bucket of █████ *ahem*, failure, of my last idea, I decided to go non-living. I meant the SCP, not me. I decided to start slow with a nonliving, simple item as a SCP. So yeah, thanks for reading this post.

Couple questions:
Martial arts is not considered hostile, can the subject wearing SCP-XXXX be taken down hand-to-hand?
If a poison is to be administered via injection, will SCP-XXXX still protect the subject?
And one more:
How does SCP-XXXX respond to "friendly actions"?

Other than a few grammatical errors peppering the article, I think it's at least fun to read.

Requiring 05 clearance for testing is a little bit high. Consider knocking it down to maybe 3 or 4.

Extreme coldness. This is the only effective way to subdue targets wielding SCP-XXXX, due to the lowered reaction time to contact, allowing target to be hurt and wounded. SCP-XXXX will still possess the property of being highly tolerant to any damage.

I don't understand what this means. Perhaps you should reword it. Also, be specific at exactly what temperature it has this effect at.
